RoamAbout Cable Assembly

The RoamAbout Cable Assembly is a proprietary cable used to connect the RoamAbout PC Card to a RoamAbout outdoor antenna system. This cable is included in the RoamAbout Outdoor Kit.

One end of the cable has a proprietary connector which is connected to the RoamAbout PC Card.

The N-Type connector at the opposite end of the cable matches the polarity of the N-connectors of the other components that are part of your outdoor antenna cabling system, subject to the country where the RoamAbout Outdoor Kit and/or Cable Assembly was purchased.
